摘要

The RYU Geothermal Field has six production wells, is a liquid dominated reservoir, the most common problem is silica scaling and flow patterns that can cause vibrations in the piping system so that it can potentially damage equipment. The effort to overcome this problem is to determine the production rate at the right well pressure. Evaluation of wellhead pressure focuses on the wellhead by considering the potential of silica scale based on the value of the SSI and the pattern of annular flow or wispy annular flow in the wellhead pressure conditions to prevent the effects of water hammer and electric power (MWe) that be generated. The SSI (Silica Saturation Index) value obtained from the output curve of the total mass rate and enthalpy with salinity correction, plot the flow pattern map with the Hewitt-Roberts model, while the potential electric power from the steam coming out of the separator using a 1 MWe correlation requires 8.2 tons /hour average vapor mass and separator pressure of 10.4115 bar or 11.2115 bar abs. The results showed that the wellhead pressure was 520-580 psi SSI value between 0.6291 - 0.6999, so there was no tendency to form silica scaling in the wellhead because the wellhead SSI value was below 1. According to the results of the Hewitt-Roberts Graph plot, under conditions wellhead pressure 520-580 psi forms an annular flow pattern or wispy annular flow at the wellhead, so it does not cause problems. At wellhead pressure 520- 580 psi has a potential between 7.65 MWe to 12.25 MWe at the pressure of separator 10.4115 bar or 11.2115 bar abs.
